Morphology

install + a + screen + door + on + a + submarine

The meaning 'attempt something that is obviously pointless or impossible' is directly inferable from the literal constituents: a screen door (which lets air through) placed on a submarine (a vessel designed to be submerged) creates an obviously impractical, incongruous image. This visual/compositional absurdity maps straightforwardly to futility and would be clear to a B1 learner who knows the component words.

Etymology

Install a screen door on a submarine creates a simple image: imagine fitting a screen door—a door with many holes—onto a submarine that must keep water out. That's why the phrase means 'to attempt something obviously pointless or impossible to achieve'.
